To all may com'em:

Be it known that I, ALBERT H. TINNER- Q MAN, a citizen of the United States residing at Cleveland, in the county of-uyahoga and State of Ohio, have invented a certain new and useful Improvement in a Stove Qven Front Frame, of which the following is a full, clear, and exact description, refer-i ence being had tothe accompanying drawlngs.

This invention relates to stoves and has for its general object the provision of a novel stove construction. directed to the maintestoves, such as kitchen ranges, with all of the enamel which is 1 various panels an nance of a uniform appearance of the exposed parts of the stove.

. It,is now the-trade custom 'to provide exposed,' exterior surfaces plated, or enam} eled to enhance the appearance of the stove as well as to afford. ease in cleaning. The usual surfacing is in the form of a vitreous parts, com rising the stove, before the stove 'is assem led. This practice has introduced many, difliculties in. the economical manufacture of those exposed enameled parts which are subjected to in ,tense heat. Thisis particularly true of the .enameled'panel portions and frame members which comprise the .front wall of the oven and door frame. For instance, where thereis a bal'nngoven su erposed over a broiler, that portion of the out frame of the stove intermediate the oven and broiler doors frequently becomes discolored by heat concentrating in the broiler adjacent thereto. This heat escapes upwardly when the broiler door;

is openedand eventually the enamel on that,

portion, of the frame tendsto discolorand,

to crack. This necessitates the replacement of the ,entire front frame 'ifYa-neat appearance is to be maintained. Considerable expense is thus incurred in dismounting the. ,damaged stove frame to substitute a'fnewa frame.

v A .more

ftherefore, is the provisionlof a front frame construction for "stoves. ofi'thei class -&1 fei'red to, which will eliminate the foregoingstated. objections to present day stove construct1ons.-

-door frame which is subjecte to the applied to and baked on the wall intermediate the top and bottom oven frame, embodying one form of my invention,

specific object a a, mafia;

influence of heat sire after be set forth-in the following descrip I ings which embody a preferred form thereof. The essential characteristics are summarized 1n the claims.

In the drawings, Fig. 1 is a fragmentary elevation of 'a front frame for a stove embodying m novelreplaceable panel constructlon; 1g. 2 1s a cross sectional side ele-. vation taken through the broiler and oven 1 of a stoye with my novel frame arrangement incorporated -m the construction thereof;

Fig. 3 is an enlarged cross sectional view corresponding to line 33 of Fig. '1 and which is taken through that ortion of the cat- .tion'which refers to the accompanying drawest heat, namely that portion disposed intermediate. the, oven and broiler doors.

In fulfilling the objects of my invention provide a frame which may be enameled on all of its exposed surfaces and which may '1 be readilyattached to the t0'p,.side and oven I panels of the stove. This frame also comprises a zjsup rting means for swingable portion of the stove comprising the front may, in one form of m invention, be formed integrally with the oven door s w 10h may be readily removed when it is desired to clean the stove. That '85 ont frame'inwhich case a re laceable panel member is provided to furnis This portion of the frame may comprise a separate readily replaceable member'which the finished or enameled efiect.

may be removed without necessitating-the removal of the front frame of the stove.

A shown in Figs. 1 and 2 a:front' stove;

may have the usual rectangular shape with top and bottom portions?- and ,8 provided-'- with, depressed, door 'engaging flanges 9.13- The flanges 9 may extend completely around" 2 the inneredges {of the frame. ,iALn-intermediate'kff'rame portion 10, constitutin that formedin:,t he Sameplane as the door contacting-facesofthe'depressed'flanges 9. l

.100 portion of the front frame: between-t e top"! oven 11, see Fig 2', and thebottom'oven .or broiler 12 may havethe'outery facethereof---- ionv The verticaliiportions =14: of-tlie franie vare provided with depressed surfacesfor the atr tachmentof, oven. door hinges and broiler fdoorhinges 15 and 16 respectively. These hinfies may be enameled or v polished as dek.

'f gt th W ietricai of the front of the ran e as well as to obtain the replaceable panel eature referred to, I provide an enameled panel member 18 which, in outer appearance conforms to the appearance of the top and bottom frame portions ordinary screw members 22 and washers 231 An annular flange 24 is provided to surround the opening 20, whereby a proper clamping seat is provided for washers 23.

The application of this frame structure to a stove construction such as is illustrated in Fig. 2, wherein the baking oven is located above the broiler so that one set of burners 27 suppillies the heat for both the broiler and the ba 'ng' oven, is particularly advantageous in that if .the enamel finish of the anel 1 8 is discolored due to heat accumuatmg- 1n the broiler adjacent the panel, the

damaged panel may be readily removed and a new. panel expeditiously substituted therefor. -ThlS ma be accomplished of course, without necessitating the dismounting of the entire front of the stove as has heretofore been the practice. If desired, the front stove frame described,

may be'formed of Pressed metal or may comprise a casting.

prefer however, to form the frame of gray iron, as gray iron castings of this character may be more readily baked during the en'ameling process. In this case,

' I provide strengthening ribs 25' and 26 on the back of the intermediate portion 10 which serve the purpose of reventing warping of the castin during the enamel baking as well as affording ledges or shoulders upon which the inner oven panel members may be 'secured. Similar ribs or lugs 27 maybe formed on the back of the top portion 7 and side portions 14.

-30 has thefront edge thereof bent 'wardl and fla ged as shown at '31 to enga As shown in Fig. 2, the top outertpanel ownthe ii 27; he outer side anels may similarl' forined to engaget e side lugs 27 ofthe ame member. Similarly,,the par titioning panel 32 which divides the interior of the'stove into the oven 11 and broiler 12- may engage the rib,25 formed on the interframe portion 10, the ten mediate casting portion '10; Int the broiler compartment immediately adjacent the ency of this 'portion of the stove frame is to'warp and dis- 1 colorfdue to its proximity to the burners and the back ofthe panel member -18'- is formed to provide an air space between the portion 10 and panel 18 to prevent the conuction of heat to the outer enameled surface 18" of the panel member 18.. As shown a art mar nal contacting portions 40 along t' e top an bottom edges of the anel 18.

Furthermore, it will be rea 'ly understood that b the use of either of the foregoing descri d constructions, it is commercially ractical for the stove manufacturer or dea' er to give a warranty with the sale of his product as to the lastln qualities of an all enameled stove with t e assurance that replacement service would involve onl a minimum expenditure commensurate wit a sales advantage which a permanency in finish and attractiveness in'ap earance affords articularly where an a ameled stove is being manufactured.

I claim:

1. In astove of the character described having a broiler oven and a top oven disosed thereabove, the combination of an integral frame comprising the front wall of the oven and broiler, a door for the top oven swingably. mounted on the frame, a similarly mounted door for the broiler said frame having an intermediate ortion dividing the frame to define the oor o enings for the oven and broiler and a re aceable white enpanel member mounted on said divi ing pormounting the frame from the stove.

3. In a cooking ran e, a front frame having a broiler oven and aking oven doorway,
